So this actually arrived a little while ago I just never got around to posting it until now. In a matter of fact these covers arrived exactly on the same day the NEW slimmer iMac was announced! XD oh well.
Anyway, they are little clips that clip onto the top of a generation 6 iMac and cover the web cam. It's a quick and easy way to turn of your webcam if you don't want to be seen and it can't be hacked . iMac Privacy Screen

I actually did choose the wsf polished. It's just that it's quite a small part and it's a close up photo so it sill looks rough but it's really smooth to the touch. I could polish it more by hand and get it to a smoother finish I suppose, but I want to show it the way people will receive it when they order it. WYSIWYG.
